|Section2= }} ''tert''-Butanesulfinamide is an organosulfur compound and a member of the class of sulfinamides. Both enantiomeric forms are commercially available and are relevant to the asymmetric synthesis of amines as a chiral ammonia equivalent.〔Organic Syntheses, Vol. 82, p.157 (2005). (Link )〕 This methodology was introduced in 1997 by Jonathan A. Ellman. ==Synthesis== Chiral ''tert''-butanesulfinamide can be prepared by enantioselective oxidation of inexpensive di-''tert''-butyl disulfide to the thiosulfinate followed by disulfide bond cleavage by lithium amide. In the original scope the chiral ligand used together with vanadyl acetylacetonate was prepared by condensing a chiral aminoindanol with 3,5-di-''tert''-butyl salicylaldehyde.
